bio Diesel

[Jay Darst]

Al,

The Diesels trucks we are having troubles with have less than 10,000
miles on them. 2 of them had 4,000 miles on them when we changed the
filters under warranty for a 2nd time.

The trucks symptoms were simply no power. Changed the fuel filter
and off they go again.

We have been cutting open the filters lately, the last 5 or 6 have
had a brownish slime coating the element.

I know for a fact that the 2 trucks mentioned were ordered by the
customers, built promptly by GM, delivered to customers within a day
or 2 of their arrival and been driven daily since using 11% Bio-
Diesel.

My service team is in contact with GM techline working on a
solution. Gm techline has informed us that they will void the fuel
system warranty on any vehicle that has more than a 5% biodiesel
mixture in its fuel system.

The DaimlerChrysler folks have sent us a bulletin that indicates
that any fuel above 5% Bio has caused the high pressure injection
pumps to fail due to lack of lubrication to the fuel pump. They too,
are voiding the pump warranty on anything over 5%.

We are in the farmimg belt, where they make 70bu/acre soybeans and
225bu/acre corn, my store is in a big farming community. I sure
would rather see us burning 100% Bio, certainly would make my buyers
buy more!

If there is a petroleum engineer on this forum who can provide us
the answer, we certainly are listening.

Thanks
